Specification of Letters Patent.

Patented Aug. 21, 191?.

Application filed October 23, 1916. Serial No. 127,217.

To all whom it may concern:

Be it known that I, EDWIN N. ANDREWS, a citizen of the United States,and a resident of Pontiac, in the county of Livingston and State ofIllinois, have invented a new and useful Heel-Expansion Shoe-Last, ofwhich the following is a specification.

The object of my invention is to provide a novel device adapted to takethe strain from the top of the lasting line of the shoe upper which isto be lasted, whereby to cause the shoe to more readily retain itsnatural shape when worn. It is further my object to pro- 1 vide a singledevice so constructed as to per form the operations which heretoforehave required the employment of two separate lasts. It is further myobject to provide a novel combination and arraugementof parts as morefully hereinafter described.

I attain the objects of my invention by the mechanism illustrated in theaccompanying drawings, in which Figure 1 is a view partly in section andpartly in elevation showing the device assembled; Fig. 2 is a top planof the invention; Fig. 3 is a vertical section; Fig. 1

is a detail of the invention partially assembled; and Fig. 5 is ahorizontal section on line 55 of Fig. 3.

Referring to the accompanying drawings illustrative of the invention, 1designates the heel portion of a wooden last having a tubular portion 2in which the tubular-memher 4 is seated. I also provide a tubularportion 3 in which stem 5 is seated. Members 4 and 5 are integral. 6designates the spindle hole. 7 designates an opening in which is mounteda suitable member 8 having a limited rotary movement, and being providedwith an arm 9 adapted to engage the end of a slidably mounted push pin10 having a limited range of movement in orificed portion 11 of member12. 13 designates the slotted portions of member 12, as shown in Fig. 4.14 designates the guide portion on which is adjustably mounted heelexpansion g depict c! this patent may be obtain d 101 block 15, abovewhich is mounted rear plate 20 which is engaged by stop latch 18, thehead 16 of which is supported by spring 17. An opening 19 beneath plate20 permits of the limited movement of heel expansion block 15. Ofcorresponding thickness with member 20 is a front plate 21, asillustrated. Suitable screws 22 secure plates 20 and 21 to the elementsupon which they are mounted. To block is secured plate which has adepending flange 23.

In operation the shoe is first applied to the last with member 8 inposition to point arm 9 laterally relative to the last, thus allowingpush pin 10 and heel expansion.

out by reason of moving member 15 to this expanded position, the objectbeing to cause the shoe to more readily retain its natural shape whenworn. I-Ieretofore it has been necessary to use two separate lasts, onelast being a half size larger than the other.

What I claim is:

1. A last having a heel expansion block the block including a platehaving a depending flange, an integrally formed stem and tubular memberrigidly mounted in the heel portion of the last and having a stop latchprojecting upward to engage the depending flanged portion of theexpansion block plate to limit its expanding movement, and means formoving the expansion block from receded to expanded position.

2. In a last, the combination with a stem and tubular element engagingin the heel of the last, of a longitudinally slidable member mounted toengage a heel expansion block, a heel expansion block having a flangedplate portion, a stop latch projecting upwardly to engage the aforesaidflange, and a rotatable member havin an arm engaging the inner end ofthe longitudinally slidable member and adapted to move that member fromreceded to extended position to operate five cents each, by addressingthe Commissioner of Patents.
